The prefrontal cortex: from monkey to man - PMC
According to Brodmann, the prefrontal cortex represents up to 29% of the surface of the human cerebral cortex, while it represents 17% and 11.5% of that in the chimpanzee and the rhesus monkey, respectively. 30 A more recent analysis indicates that the proportions of grey and white matter in the human prefrontal cortex are 1.9–2.4-fold that ...
Evolution of prefrontal cortex - PMC - PubMed Central (PMC)
Subdivisions of the prefrontal cortex (PFC) evolved at different times. Agranular parts of the PFC emerged in early mammals, and rodents, primates, and other modern mammals share them by inheritance. These are limbic areas and include the agranular orbital cortex and agranular medial frontal cortex (areas 24, 32, and 25).
What constitutes the prefrontal cortex? | Science - AAAS
2017年10月27日 · For 70 years, the prefrontal cortex has in essence been defined as the part of the cerebral cortex that receives projections from the mediodorsal nucleus of the thalamus (MD). The core of this concept can be traced back to Rose and Woolsey (7).
